RtHz scaling, 386K sampling and maybe more

I am confused about the grayed out options in the QA40x application. Specifically, I’d like to take advantage of the RtHz scaling on the dBV options (for which I found a forum post related to the 401 analyzer) and the 384K sampling. Are these options functions that are obsolete for the 403 analyzer or placeholders for future development, or is there some combination of settings that enable them?

I try not to be the new-guy burden in forums, but I’m not finding any documentation about it.

Thanks in advance for any advice.

Just added as an issue. Thanks for reporting.
